If you wanted another power-supply, I remember hearing that the CD32 power supply was the ones originally made for the C65.. infact your photo is identical to my CD32 supply, even down to the sticker underneath which also says "PSU C65".
It also is the same Power Supply that the 1581 3.5" floppy drive used. Possibly also the 1541-II. Seems Commodore was trying to consolodate their power supply types at the time to cut costs so were reusing them where possible on different systems.
